With Michigan’s public school districts facing a decline in per-pupil funding, more districts are contracting out for at least one of the three major school support services — food, custodial and transportation — than ever before. This year’s survey of school districts found that 44.6 percent of all Michigan school districts contract out for at least one of these services, a 5.6 percent increase over 2008. This year, new contracts alone are expected to save $6.9 million.
